Divide (3+2i)/(-4+5i). express answer in standard form
Levart [38]
\dfrac{3+2i}{-4+5i}=\dfrac{(3+2i)(-4-5i)}{(-4+5i)(-4-5i)}=\dfrac{-12-15i-8i-10i^2}{(-4)^2-(5i)^2}\\\\=\dfrac{-12-23i+10}{16+25}=\dfrac{-2-23i}{41}=-\dfrac{2}{41}-\dfrac{23}{41}i

Graph the system of equations using technology. What is the x-coordinate of the solution? Round to the nearest hundredth.
Fiesta28 [93]

The x - coordinate of the solution is x=5.83

Explanation:

The two equations are $2 x-11 y=4$ and $3 x-5 y=14$

The image attached below shows the solution of the two equations.

The x - coordinate of the solution can be determined using substitution method.

Let us substitute $3 x-5 y=14$ ⇒ y=-\frac{(14-3x)}{5} in the equation $2 x-11 y=4$

Thus, we have,

2x-11(-\frac{(14-3 x)}{5})=4

Simplifying, we get,

2x+\frac{154}{5}-\frac{33x}{5}  =4

Adding the like terms, we have,

    -\frac{23x}{5} +\frac{154}{5}  =4

\frac{1}{5} (-23x+154)=4

Multiplying both sides by 5, we have,

-23x+154=20

         -23x=-134

               x=5.826

Rounding off to the nearest hundredth, we get,

x=5.83

Hence, the x - coordinate of the solution is x=5.83
